To all whom it may camera: A

Be it known that I, JUSTUS R. KINNEY, a. citizen of the United States ofAmerica, and a resident of Boston, in the county of Suflolk and State ofMassachusetts, have invented certain new and useful Improvements inControl for Sewage and. other Pumps, of which the following is a specification.

This invention relates to automatic sewage ejectors, and has for itsobject the production of an apparatus especially adapted for pumpingsewage from buildings having basements below the level of the sewer.

The invention consists of certain novel features of construction andarrangement of parts which will be readily understood by reference tothe description of the drawings and to the claims hereinafter given.

Of the drawings: Figure 1 represents a plan view of an apparatusembodying the features of the present invention. Fig. 2 represents avertical section of the same, the cutting plane being on line 2, 2 onFig. 1, and Fig. 3 represents a horizontal section of the same, thecutting plane being on line 3, 3 on Fig. 2.

Similar characters designate like parts throughout the several figuresof the drawmgs.

In the drawings 10 represents a pit or chamber in the basement of abuildin from which the sewage is to be remove Po sitioned within the pit10 are two reservoirs or tanks, 11 and 12,- each having an inclinedbottom, 13. The extreme lower ends of the reservoirs 11 and 12 areconnected by means of a valve 14, having a valve stem 15, extendingupwardly above the pit cover 16 and provided at its extreme u per endwith a handle 17, by which said va ve 14 may be.

operated to shut off the communication between said reservoirs or tanks11 and 12, or open the assage from one tank to the other, as desired. Aninlet pipe, 18, communicates with the interior of the tank 11, and asimilar inlet pipe 19, communicates with the other tank 12.

Within the tanks 11 and 12 and opposite the mouths of the inlet pipes 18and 19, are woven baskets 20. These baskets 20 are made up of wire meshwith the bottoms of the baskets some distance below the mouths of theinlet pipes 18 and 19, so that any solid substance entering the tanks 11and ings. These baskets'20 are slidably mounted in the ides 21 formed uon or secured to the inner wall of the tan lzs 11 and 12, and eachbasket is provided with a handle 22 by which it may be moved upwardl onthe guides 21, and throu h the hand-ho e in the cover 16 said hanholes-being normally covered by removable plates 23.

A suction pipe 24 communicates with the extreme lower end of eachof thetanks 11 and 12, and extends upwardly in the pit 10 through the pitcover 16, said suction pipe 24 being provided with a valve 25 of anywell-known construction -adapted to regulate the flow of materialthrough said pipe. The upper end of the pipe 24 is connected to a rotarypump 26 which ump is provided with an outlet 27. Eac pump 26 is providedwith a drivin shaft 28 which is driven by a suitable engine 29.Preferably, and as indicated in the drawings, this engine is a rotaryengine, and the two en- .gines 29 are connected by pipes 30 to a commonexhaust'pipe 31. Each engine 29 has an independent steam inlet pipe 32,communicating with a balanced valve 33. The outlet pipe 34 from saidbalanced valve communicates with a governor 35, of any welbknownconstruction, and this governor 35 is provided with an outlet pipe 36communicating with and supplying steam to the engine 29. 'On each shaft28 is secured a. pulley 37, connected by a belt 38 to the pulley 39 onthe governor 35, so that any rotary movement of the shaft 28 is impartedto thegovernor 35 inthe usual manner, and regulates the flow of themotive agent from the pipe 34 to the pipe 36. In the bottom of the pit10 is a depression 40, into which extends the lower end of the pipe 41connected to the pipe 24 and provided with a valve 42. It is obviousthat when the pump is in operation and the valve 42 is open the pit maybe pumped out. Normally the valve 42 is closed and all sewage iscontained within the tanks 11 and 12, each of which is provided with itsindependent pumping apparatus.

By closing the valve 14 each system may be operated independently of theother, the inlet pipe 18 carrying sewage to one of the tanks from onepart of the building, and the inlet pipe 19 carrying sewage from anotherpart of the building to the other tank. 'It'is also possible that bothinlet pipes 18 and 19 may care for the sewage from all parts of thebuilding, or one pipe may be closed and the other remain open, therebyusing only one tank 11 or 12, as

desired, aifording an opportunity to clean out or repair the other. tankor its pumping apparatus. In case, however, the sewage flows in toogreat a quantity for one tank 11 or 12 and its pumping apparatus to takecare of it, the valve 14 may be'opened and the sewage collected in bothtanks.

Depending from the under side of the cover 16 into each of the tanks 11and 12 is a tubular guide member 43, in which is mounted a float-44having a stem 45 extending upwardly through the cover 16. Adjustablymounted upon the stem 45 are the projecting members 47 and 48, which areadapted in the vertical movement of the stem'45, due to the rise andfall of the float 44 to engage with the controlling lever 49 forregulating the operations of the balanced valve 33. It is obvious,therefore, that by adjusting these projections 47 and 48 on the stem 45and locating them in predetermined positions, whenever the level of thesewage in the tank 12 reaches a given point carrying the float 44therewith, the projection 48 will engage the controlling lever 49 of thebalanced valve 33 and cause it to operate to admit steam to the engine29, thereby operating the pump 26 for the purpose of removing the sewagefrom said tank. As this is accomplished the float 44 will gradually dropto such a level as will cause the projection 47 to engage thecontrolling lever 49 andcause the operation of the balanced valve toshut off the supply of steam to the engine 29, and thus cause thepumping to cease.

When the valve 14 is open, thus providing communication from one tank 11to theother 12, and the sewage flows so rapidly into the tanks -11 and12 that a single pump is incapable of removing it as quickly as it onters said tanks, it is desirable that some automatic arrangement beprovided for placing in action an additional pump.

This can readily be accomplished'by providing the float stem 45 withadjustable projections 47 and 48" that will engage the, controllinglever 49 on the balanced valve 33 a little later than the contact ismade between the projection 48 and the controlling lever 49. In otherwords, if the projection 48 engages with the controlling lever 49 of thebalanced valve 33, and sets into'ope'ration one'pump, and this pump iscapable of carrying ofl the sewage entering the tanks as fast as it isdeposited therein, the projection 48 will never contact with thecontrolling lever 49*, and one pump will therefore remain at rest, butif the supply of sewage enters the tanks more rapidly than the singlepump canremove it from the tanks, it is obvlous that the level of thesewage in the tanks will continue to rise, thereby lifting theprojection 48 to such a point as to engage the .con-,

trolling lever 49 and cause the other pump to be placed in operation.The two pumps will then continue in operation until the level of thesewage is lowered sufficiently for the projections 47, 47* to engage thecontrolling levers 49, 49* thereby stopping the pumps.

It is believed that the operation and many advantages of a device ofthis construction will be readily understood without any furtherdescription.
